To all whom it may concern.-

Be it known that I, CHARLES L. SILLBY, citizen of the United States, residing Marys, in the count}, of Auglaize and State of Ohio, have invented certain new and use ful Improvements in Nater-llEetcrs; and i do declare the following to be full, clear, and exact description of the invention, such as Will enable others skilled in the to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

i This invention relates to improvements in -Water meters. The object of the invention is to provide a Water meter which is operated in a common manner by the water passing through the meter through the employment of mechanisms by which a minimum of resistance is oiiiered and by which ll am enabled to reduce the comparative size of the meter as a Whole. In accomplishing the purposes of my improved Water meter, 1

provide a maximum of leverage between the piston and the register whereby the loss due to friction of the stuiiing box is overcome. In the accompanying drawings'l igure l is a horizontal sectional view of the meter on the line 1-i of Fig. 2; Fig. 2 is a vertical sectional view on the line 2-2 of Fi 1; Fig. 3 is a sectional View of the escapement on the line 3-3 of Fig. 2. In the detailed description of the invention, similar reference characters indicate corresponding parts in the drawings.

The casing consists of a bottom portion 1 having inlet and discharge nipples 20 and 21 respectively, and a top portion 2 which is attached to the bottom portion 1 by a suitable number of cap screws 22. The top portion 2 has an oifset :2 on one side to provide the necessary space for the transmission devices to be presently described. A door 8 hinged at 8 ineloses an opening in the top of the casing through which a convenient form of register dial 9 is viewable. This dial is operated from a worm shaft 10 in a Well known manner, and the present improvements relate to the mecha nism for actuating this Worm shaft 10 from the piston. The piston consists of a disk 5 and ball 6, which parts are integral and have a rolling movement under the force of the Water passing through the meter. The ball portion of the piston seats Within s ecification of Letters P Application flied February i5. 191?. Serial l'o.

a concavod recess in the bottom 3 of the piston housing The parts 3 and t c constitute a casing which is mounted Within lower portion of the meter casing. The of the piston housing is also closed b, tapered cover 12 which has an opening 1n the portion thereof that lies YESOVQI the body 6 of the piston. The body i i135 mou'rted in it a stem 1% which projects through the opening 13 and extends above the housing of the. piston where it engages a guide, consisting oi a tapered head 15 which projects down from a horizontal division Wall 16 that separates the upper portion 2 of the casing into two compartments A. and L. The stem 1% has an drbital movement under the rocking motion imparted to the piston'by the Water passing through the meter. The upper compartment is to accommodate the registering devices and the transmission devices therefonand the lower portion 13 provides the Water passage through the meter and space in which the piston housing is placed. The head 15, as before stated, has tapered surface and serves to guide the stem is; as it is moved thercaround by the rolling action of the piston. 17 designates forked arin lever which receives the upper end of stein i l. The length. of the forked end or said lever l? is such that the stem 1% is confined Within said. fork when. moving a blind the tapered guide 15. The leverili' is of suitable form and has fulcrum at 18 on'a 19 which projects down from the division wall 16. 9.7 designates an upright shaft mounted in a stuiiiug box 22 formed on the division Wall 16 and projecting upwardly and downwardly from the plane ofszml division Wall. Fixed to the upper end of this shaft 27 is the forked member 23 which constitutes a feature of the osc pement dovice, the other feature of which is a crown wheel 2% which is fixed to the Worm shaft 10 through which the meter dial 9 is open ated. The crown teeth of the gear 9. L are tapered outwardly, as shown in Fig. 3 where 25 indicates the teeth proper. The prongs of the escapenicnt member 23 have fiat sides that move in parallel relation with the pered sides of the tcct l and as the shaft 2? is oscillated from the lever the operation of the Worm shaft it) is similar to that of an escapcment movement.

The lower end of the shaft. 27 has hired to it an oscillating crank 26 an end of which is flexibly connected to the adjacent end of the lever 17. It will therefore be seen that the movement transmitted to the lever 17 from. the piston pin 14 Will be imparted to the shaft 27. The movement imparted from the 'vston pin 1: to the shaft 27 is instrumental moving the prongs of the escapement ember alternately in and out of mesh With the opposite teeth of tie escapement is member 24-, The transmission lever 17 affords ample leverage for accurately moving the dial devices through the escapement members, and overcomes the friction of the stuffing box 22 to a desirable extent. This manner of transmitting the movement of the Water actuated piston to the registering dial also enables the size of the meter as a whole to be confined Within desirable limits.

Having described my invention, I claim:

1, In a Water meter, the combination of an outer casing, an inner casing providing a Water passage, a disk piston mounted in said water passage, a movement transmission stem'projected from said piston, a guide for the upper end of said stem, a lever actuated by said stem, a shaft actuated from said lever, and escapement devices actuated from said shaft and through which the meter dial is operated to. indicate the flow of water through the meter.

2. In a water meter, the combination of a casing providing a water passage, a disk piston mounted in said passage, a transmission stem secured to said piston and having an orbital movement, a lever actuated by said stern, an upright shaft, a link connecting lever and adapted to actuate said shaft, cs-' capement devices actuated by said shaft, and a worm shaft actuated by said escapement devices and through which the meter indicator or register is operated from the movement of the piston.

l. In a water meter, the combination of a casing providing a water passage, a disk piston mounted in said casing, a stem projected from said piston, a tapered guide engaging the upper end of said stem and between which and the top of said casing the movement of said stem is confined, a bifurcated lever actuated by said stem, an upright shaft, a connection between said upright shaft and said lever whereby the shaft is operated from the lever, escapemcnt devices comprising a forked member fixed to said shaft, a crown wheel actuated by said escapement, and a worm shaft actuated from said crown wheel and through which movement is imparted to the meter register, substantially as specified.

In testimony whereof I afiix my signature.
